The gas is inert and prevents contamination etc through exposure to air, also better heat control I think.
I have used welders all my life, arc, mig and tig, and for home auto use I would strongly suggest a mig. Better welds, easier to use on thin metal and you can also weld aluminium if you use aluminium wire (buy argoshield as though, not the cheaper migshield) Regards Brad Hallett http://www.powerup.com.au/~bhallett http://www.datrats.com.au for the best in Nissan Motorsport Equipment -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Adam Jackson Sent: Sunday, 18 November 2001 9:58 AM To: [EMAIL PROTECTED] Subject: Re: off topic : welding equipment Thanks for the reply. The mig i'm looking at doesn't require gas http://www.cigweld.com.au/pages/images/product/welding/022.pdf Sorry if this is a stupid question, but what is the gas for? and would the above mentioned welder be appropriate for my needs?
